摘　　要：利用LI近期提出的平顶光束新模型 ,推导出平顶光束通过傍轴ABCD光学系统传输后光场分布的解析公式。以透镜系统为例 ,给出了平顶光束聚焦场分布的解析表达式 。Making use of the new model of flat-topped light beams proposed by LI recently,the analytical expression of the field distribution of flat-topped light beams passing through a paraxial ABCD optical system has been derived. The lens system is taken as an example,the analytical expression of the focusing field distribution of flat-topped light beams is given. The focusing properties of flat-topped light beams have been analyzed in detail.
